	Eduard Oscar Schmidt Eduard Oscar Schmidt (21 February 1823, in Torgau – 17 January 1886, in Kappelrodeck) was a German zoologist and phycologist. Biography He initially studied mathematics and science at Halle, then continued his education in Berlin, where he came under the influence of Christian Gottfried Ehrenberg and Johannes Peter Müller. In 1847 he received his habilitation at the University of Jena, becoming an associate professor during the following year. In 1855 was he appointed professor of zoology at the University of Cracow. Later he taught classes at the Universities of Graz (from 1857) and Strasbourg (from 1872). Schmidt was an early proponent of Darwinian evolutionary thought. He is remembered for his research of Porifera (sponges), particularly species from the Adriatic Sea. Schmidt also made contributions in the field of phycology. As far back as 1862 Oscar Schmidt showed that "cuttings" of sponges will attach themselves and grow. This idea was followed through in the exp ...

picture info	Demosponge Demosponges (Demospongiae) are the most diverse class in the phylum Porifera. They include 76.2% of all species of sponges with nearly 8,800 species worldwide (World Porifera Database). They are sponges with a soft body that covers a hard, often massive skeleton made of calcium carbonate, either aragonite or calcite. They are predominantly leuconoid in structure. Their "skeletons" are made of spicules consisting of fibers of the protein spongin, the mineral silica, or both. Where spicules of silica are present, they have a different shape from those in the otherwise similar glass sponges. Some species, in particular from the Antarctic, obtain the silica for spicule building from the ingestion of siliceous diatoms. The many diverse orders in this class include all of the large sponges. Most are marine dwellers, but one order ( Spongillida) live in freshwater environments. Some species are brightly colored, with great variety in body shape; the largest species are ove ...

	Crellidae Crellidae is a family of marine demosponges in the order Poecilosclerida. Characteristics Growth forms are varied and include branching, club-shaped, massive and encrusting. Identification of members of this family is based on microscopic examination of the spicules in their skeleton. The choanosomal A choanosome is an inner region of a sponge, supported on the choanoskeleton, the stucture that contains the choanocyte Choanocytes (also known as "collar cells") are cells that line the interior of asconoid, syconoid and leuconoid body types of ... skeleton is composed of tornotes while the ectosomal skeleton consists of a tangential crust of spined styles or oxeas. The microscleres are mostly arcuate isochelae.

picture info	Poecilosclerida Poecilosclerida is an order of the demosponge class. It is the most speciose demosponge order with over 2200 species (World Porifera Database). It contains about 25 recognised families. They are characterised by having chelae microscleres, that is, the minute spicules scattered through the tissues, usually in the 10-60 μm range, have a shovel-like structure on the end. Most of the families are viviparous with parenchymella larvae that are uniformly ciliated The cilium, plural cilia (), is a membrane-bound organelle found on most types of eukaryotic cell, and certain microorganisms known as ciliates. Cilia are absent in bacteria and archaea. The cilium has the shape of a slender threadlike projecti .... Families As of 2018, the following families are recognized: References {{demosponge-stub ...
